Merge tag 'spi-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "A quiet release, more bug fixes than anything else.  A few things do
  stand out though:

   - updates to several drivers to move towards the standard GPIO chip
     select handling in the core.
   - DMA support for the SH MSIOF driver.
   - support for Rockchip SPI controllers (their first mainline
     submission)"
